  • Ethylene anesthesia

    Ethylene given as a combination of oxygen 20%, cyclopropane 10%, and ethylene 70%,. Because it is a rather weak anesthetic, and volatile and inflammable, it is rarely, if ever, used.  

  • Endotracheal anesthesia

    Anesthesia in which gases are administered via a tube inserted into the trachea.  

  • Electronic dental anesthesia

    In dentistry, the use of low levels of electric current to block pain signals en route to the brain. The patient controls the current through a hand-held control. The current creates no discomfort and, unlike local anesthesia, leaves no numbness to wear off once the dental work is completed.  

  • Electric anesthesia

    Anesthesia induced with electric current.  

  • Anesthesia dolorosa

    Pain in an anesthetized zone, as in thalamic lesions. Intense pain in a specific body part that is simultaneously unresponsive to touch. This phenomenon is observed in specific spinal cord disorders.  

  • Dissociative anesthesia

    A type of anesthesia marked by catalepsy, amnesia, and marked analgesia. The patient experiences a strong feeling of dissociation from the environment.  

  • Crossed anesthesia

    Anesthesia of the side opposite to the site of a central nervous system lesion.  

  • Closed anesthesia

    A method of inhalation anesthesia in which exhaled gases are rebreathed. This requires appropriate treatment of the exhaled gas to absorb the expired carbon dioxide and to replenish the oxygen and the anesthetic.  

  • Central anesthesia

    Pathological anesthesia due to a lesion of the central nervous system.  

  • Bulbar anesthesia

    Anesthesia produced by a lesion of the pons.
